This shows in the tracker as assigned to Hans, but Hans signed off a week ago.

Henri objected, and I agree, that we need to understand what's going on,
and in particular why 48 would be the correct size.

Valgrind ignores the rounding mode:

Valgrind, setting RC_DOWN:
writer.c:364: Test failed: 2097: got 39 expected 22
writer.c:366: Test failed: 2097: got <t>100000000000000.0156249999999999</t> expected <t>100000000000000</t>

no Valgrind, not setting RC_DOWN:
writer.c:364: Test failed: 2097: got 39 expected 22
writer.c:366: Test failed: 2097: got <t>100000000000000.0312499999999999</t> expected <t>100000000000000</t>

32 characters will be needed at most (excluding XML tags) because the
formatting code switches to exponential notation beyond 1^14 and precision
is capped at 0.0000000000000001, or 16 digits.

Thanks for looking into this. Could you please resend a patch with the
correct size and an appropriate comment?
